The hx83102j is a TDDI IC (Touch with Display Driver). The IC using SPI to transferring HID packet to host CPU. The IC also report HID report descriptor for driver to register HID device. The driver is designed as a framework for future expansion and hx83102j is the first case. Each hx_spi_hid_hx8xxxxx modules are mutual exclusive, it should be initiate one at a time. This driver takes a position similar to i2c-hid, it initialize and control the touch IC below and register HID to upper hid-core. When touch ic report an interrupt, it receive the data from IC and report as HID input to hid-core. Let hid-core dispatch input to registered hid-protocol and report to related input sub-system. This driver also provide advanced functions by hidraw interface: - runtime firmware update - debug functions, such as reg r/w - self test for touch panel Due to patch size is too big, separate into 3 part. This is part 2.
